Explanation
Anti-affinity rules instruct the hypervisor scheduler to place specified VMs on different physical hosts. If one hypervisor fails, VMs on other hosts continue running, ensuring the application remains available. Affinity rules (D) do the opposite - they co-locate VMs on the same host, which creates a single point of failure. Cold migration (B) moves a powered-off VM and does not address availability. Live migration (C) moves a running VM with minimal downtime but is a reactive/manual operation, not a high-availability policy that protects against host failure automatically.
